Mathematical modeling of oil transportation by pipelines using anti-turbulent additives
(Journal of vibroengineering, 2013)The energy costs of oil transportation by pipeline are one of the most important questions for oil companies. Large amounts of energy are used in the oil pumping process. One of the ways to reduce energy costs is to use ... -
Measurement of large amplitude plane vibrations of two dimensional structures
(Journal of measurements in engineering / Lithuanian Academy of Sciences, Kaunas University of Technology, Vilnius Gediminas Technical University, 2016)In the paper large amplitude plane vibrations of an elastic structure are investigated experimentally by using the method of time averaged geometric moire. Investigations of a two-dimensional problem are performed. ... -
Piecewise constant control of a precise measurement platform
(Journal of measurements in engineering / Lithuanian Academy of Sciences, Kaunas University of Technology, Vilnius Gediminas Technical University, 2016)Control of a precise measurement platform is investigated in this paper. Piecewise constant control procedure on the basis of finite element in time and the method of least squares is proposed. It is demonstrated that the ... -
